I’ve notice my mucus pattern has changed dramaticaly. I am producing lots of mucus.Everyday is a thin clear mucus day.There is no change in odor. At first I thought this might be an early sign of pregnancy but my period has come and gone. I also took an at home pregnancy which turned out negative. Please help. I am worried I might have cancer.

I am 36wks today. Noticed two times today a gush of watery fluid. No color or odor to it. Braxton Hicks contractions are no different than they have been over the past several months. This is my 3rd pregnancy and I didnt experience this with the previous two. I also noticed today that when bent forward to make my son’s bed my breast began leaking. Also never had that occur before. I did not pass the mucous plug as of yet.
I have a dr. appt tomorrow. Should I just wait until then to address it with her or could it be pre-term labor?
The braxton hicks are occuring all of the time and have been for months. Obviously the further along I get the more intense they get.
I also have had several BM’s today which is abnormal for me.
